Yeah but depending on when you bought the game you could have v191 or v192. If you have v192, please download the game again to get v191 since v192 has a header issue.

I bought it last week on Tuesday February 12th.  Can't check which version I have at the moment.
 

OK, Rainwarrior at the NesDev forums came up with the answer to making the Twin Dragons ROM work on the PowerPak using Bananmos's Mapper 30:

"Looking at Bananmos' verlog, it looks like it supports 1-screen and 4-screen but the assignments are backwards, unfortunately. So, if you have a hex editor, you can change a single bit in the ROM to make it work with the backwards assignment. Byte $6 (the 7th byte) of the iNES ROM should be $E8. Change it to $E9 and it should work."

And lo and behold, it does!

Load the Twin Dragons ROM into a hex editor and the first eight bytes read thusly:

4E45531A 2000E810

Change the 7th byte from E8 to E9 so that you have:

4E45531A 2000E910

Save the file, load onto your PowerPak, and presto! It now works using Bananmos's Mapper 30. All you PowerPakkers may now buy the ROM with confidence; it just needs a quick edit!
